The terpolymer resins have been prepared by polycondensation of vanillin (V) and chloro=bromo-substituted acetophenone (CA=BA) with furfural (FU) in the presence of 1 M HCl in 1:1:2 molar proportions. The characterization and structural elucidation of terpolymers were confirmed by FT-IR, pyrolysis GC-MS, and non-aqueous conductometric titration. Activation energy during curing process was determined by the Kissinger method, whereas thermal decomposition was determined by the OzawaFlynn-Wall method. Both terpolymer resins have shown excellent antimicrobial activity as compared to the standard ciprofloxacin and amphotericin-B drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
